Cheerleading is a physical activity, sometimes a competitive sport, based on organized routines, usually ranging from one to three minutes, which contain the components of tumbling, dance, jumps, cheers, and stunting to direct spectators of events to cheer on sports teams at games or to participate in competitions. The athlete involved is called a cheerleader. Cheerleading originated in the United States, and remains a predominantly American activity, with an estimated 1.5 million participants in all-star cheerleading. The growing presentation of cheerleading as a sport to a global audience has been led by the 1997 start of broadcasts of cheerleading competition by ESPN International and the worldwide release of the 2000 film Bring it On. Due in part to this recent exposure, there are now an estimated 100,000 participants scattered around the rest of the world in countries including Australia, Canada, China, Colombia, Finland, France, Germany, Japan, the Netherlands, New Zealand and the United Kingdom.
